E: 包 'python-scipy' 没有安装候选

  • 772

安装软件后，我多次发现以下错误：

$ sudo python setup.py install
Traceback (most recent call last):
  File "setup.py", line 24, in <module>
    from software_name import PACKAGE_NAME
  File "/home/username/Softwares/software_name/__init__.py", line 29, in <module>
import scipy
ImportError: No module named scipy

我可以安装许多缺少的模块，例如sudo apt-get install -y python-numpy，但有时我会得到：

username@username:~/Softwares/software_name$ sudo apt-get install -y python-scipy

Package python-scipy is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'python-scipy' has no installation candidate

我真的不确定发生了什么？我在另一个线程上读到 20.04 LTS 存储库有 NumPy，但没有 SciPy。

编辑：

$ sudo apt install python-pip

However the following packages replace it:
  python3-pip

E: Package 'python-pip' has no installation candidate

$ pip install scipy
Requirement already satisfied: scipy in /usr/lib/python3/dist-packages (1.3.3)

$ sudo apt install python3-pip

python3-pip is already the newest version (20.0.2-5ubuntu1.6).

    在 ubuntu 存储库中查找包的最佳来源是packages.ubuntu.com

    你可以搜索 scipyuniverse会看到，它是从18.04 之后取出的。

    我只能推测原因，也许找不到该软件包的维护者。

    但是，您可以通过以下方式轻松安装它pip：

    sudo apt install python3-pip
pip install scipy

    请注意，这pip将默认为您的本地用户安装软件包。如果您需要与其他用户或其他用户一起运行python脚本sudo，则需要在系统范围内安装它：

    sudo pip install scipy

    如果您python仍然无法识别包裹，您可能需要检查是否python有链接到python2. 检查与python --version。
